READ OPERATIONS

Immediate Read

To read data from memory, the Master creates a START

condition on the bus and then broadcasts a Slave ad-

dress with the R/W

dress with the R/

dress with the R/ bit set to ‘1’. The Slave responds with

W

ACK and starts shifting out data residing at the current

address. After receiving the data, the Master responds

with NoACK and terminates the session by creating a

STOP condition on the bus (Figure 9). The Slave then

returns to Standby mode.

Selective Read

To read data residing at a speciﬁc address, the selected

address must ﬁrst be loaded into the internal address

register. This is done by starting a Byte Write sequence,

whereby the Master creates a START condition, then

broadcasts a Slave address with the R/W bit set to ‘0’

and then sends two address bytes to the Slave. Rather

than completing the Byte Write sequence by sending

data, the Master then creates a START condition and

broadcasts a Slave address with the R/W

broadcasts a Slave address with the R/

bit set to ‘1’.

W

The Slave responds withACK after every byte sent by the

Master and then sends out data residing at the selected

address. After receiving the data, the Master responds

with NoACK and then terminates the session by creating

a STOP condition on the bus (Figure 10).

Sequential Read

If, after receiving data sent by the Slave, the Master

responds withACK, then the Slave will continue transmit-

ting until the Master responds with NoACK followed by

STOP (Figure 11). During Sequential Read the internal

byte address is automatically incremented up to the end

of memory, where it then wraps around to the beginning

of memory.
